Find the perimeter and area

Mathematics

Answer:

P = 27.9

A = 27.25

Step-by-step explanation:

First we find the base using pythagorean theorem

c² = a² + b²

12² = 5² + b²

144 = 25 + b²

b² = 144 - 25

b² = 119

b = √ 119

b = 10.9

Perimeter = a + b + c

5 + 10.9 + 12 = 27.9

Area = 1/2 × b × h

A = 1/2 × 10.9 × 5

A = 54.5/2

A = 27.25

Therefore P = 27.9

A = 27.25

Answer:

Area: 30 Perimeter: 22

Step-by-step explanation:

To find the area of the triangle you need to multiply the base and the length, which is directly perpendicular to the base. After multiplying, you will divide the product by 2 to get your answer, this is because a triangle is half a rectangle.

For the perimeter, I assumed that the empty side was a 5, please correct me if I am wrong. But to find the perimeter you need to add all the sides together, so I got 22.

How does the Counting Principle help when determining the sample space for a probability distribution?
andreyandreev [35.5K]

Answer:

This is also known as the Counting rule.

The Fundamental Counting Principle is used in determining all the possible outcomes and the total possible ways different events can be combined with each other. It is usually done by multiplying all the events together to get the total possible outcome. Doing this also helps in determining the sample space of a probability.

For example there are events a, b and c. The total sample space or possible outcome will be a*b*c.

Four times the greater of two consecutive integers is 18 more than three times the lesser integer. What are the integers?
maw [93]
This is how I would solve it:

1st # = x                 4(x+1)=3x+18
2nd # = x+1              4x+4=3x+18
                                     4x=3x+14
                                       x=14

To check: 15x4=60; 60-42=18.       <u>1st # = 14; 2nd # = 15.</u>

Chris and Becky are comparing mortgages. The mortgage is for $183,500. If they choose 30 years at 5%, their monthly payment will
soldi70 [24.7K]

Answer:

For 30 years at 5% = $354,625.2

For 20 years at 4.5% = $278,618.4

Step-by-step explanation:

The total payback for each payment is given by the monthly payment multiplied by the total number of months for the payment period (years).

1) For 30 years at 5%

Total number of months in 30 years = 30 x 12 = 360 months

Payback = $985.07 x 360 = $354,625.2

2) For 20 years at 4.5%

Total number of months in 20 years = 20 x 12 = 240 months

Payback = $1160.91 x 240 = $278,618.4

A sum of money is shared among Ben, Jack, and Sarah in the ratio 6 : 8 : 10.
alexdok [17]

Answer:

B:J:S

6:8:10

6+8+10= 24 parts all together

Sarah has $50 and equals 10 parts. So, each part is worth $5. (50/10=5)

Thus, Ben receives 6 parts, with each part being $5. So, Ben gets $30. (6x5=30)
